Front

What is Pangea?

Back

Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all the continents were joined together.

What is the Continental Drift Theory?

Back

The Continental Drift Theory is the theory that states that the continents have moved over geological time and were once joined together in a single landmass.

What are divergent plate boundaries?

Back

Divergent plate boundaries are areas where tectonic plates move away from each other, often resulting in the formation of new crust.

What are convergent plate boundaries?

Back

Convergent plate boundaries are areas where tectonic plates move towards each other, often leading to subduction or mountain formation.

What are transform plate boundaries?

Back

Transform plate boundaries are areas where tectonic plates slide past each other horizontally, causing earthquakes.

Why was Wegener's theory initially rejected?

Back

Wegener's theory was rejected because he could not provide a convincing explanation for how the continents moved.

What is the significance of glacier scars found in Africa?

Back

Glacier scars in Africa indicate that the continent was once located in a much colder climate, supporting the idea of continental drift.

What role do tectonic plates play in Earth's geology?

Back

Tectonic plates are large sections of the Earth's crust that move and interact, causing geological phenomena such as earthquakes, volcanic activity, and mountain building.

What is the process of subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often leading to volcanic activity.
